kernel/watchdog: fix Kconfig constraints for perf hardlockup watchdog
Commit 05a4a9527931 ("kernel/watchdog: split up config options") lost
the perf-based hardlockup detector's dependency on PERF_EVENTS, which
can result in broken builds with some powerpc configurations.
Restore the dependency. Add it in for x86 too, despite x86 always
selecting PERF_EVENTS it seems reasonable to make the dependency
explicit.
